如何解决TypeError: expected string or buffer？

Question

求助代码
import urllib2
import re
import os
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:67.0) Gecko/20100101 Firefox/67.0", }
urlcontent = urllib2.urlopen('http://news.qq.com/a/20120506/index.htm')
#print urlcontent
rege = re.compile(r"/a/\d{8}/\d{6}.htm")
get_url = re.findall(rege,urlcontent)
print get_url

exit()

会报错
